679d000446 Add possibility to boot without init (#164)
* Add possibility to boot without init(rd,ramfs):
  - For a snapshot to be valid, it must contain a boot folder and a kernel from the official list (or have been added to the custom kernel list)
  - if a snapshot doesn't contain an init(rd,ramfs), it will be detected as valid.
  - Suppress script stop when an init is not found
  - If init isn't found, add the letter "x" to the init list. (hoping this doesn't break the support for custom init names)
  - The microcode support is still present, despite the absence of init(rd,ramfs), is it really relevant ?

83bf1da01e Improves systemd.path unit (#139)
* grub-btrfs.path : improves unit

#### Remember to modify your configuration accordingly.  
Allows the unit to start and stop automatically when the mount point is detected.  
If the mount point is already mounted when the unit is activated `systemctl enable grub-btrfs.path`,  
it will be necessary to start the unit for monitoring to begin `systemctl start grub-btrfs.path`.

- `DefaultDependencies=no`
Prevents systemd from automatically generating `Wants= or Requires= or After=`.
- `Requires=\x2esnapshots.mount`
Ensures unit is started if mount point exists.
- `After=\x2esnapshots.mount`
Unit start after the mounting point exists.
- `BindsTo=\x2esnapshots.mount`
If the mount point is removed, the unit will stop.
- `PathModified=\x2esnapshots.mount`
The monitored folder containing the snapshots.
- `WantedBy=\x2esnapshots.mount`
If the mount point exists, unit start automatically. (only if unit is activated before the mount point is mounted)

* Readme: Update "Automatically update grub" section

Update section following the recent change in the `grub-btrfs.path` unit.  
Add information to be able to update the `grub-btrfs` menu every time the system is restart/shutdown.

2f22fd8630 [make help] mention INITCPIO switch (#137)
This commit is an expansion to :
87b816345b

Since a new `make` parameter has been introduced, it should be mentioned
in the output of the `help` target.

Also, the table is being expanded by a new column describing the type of
data that each parameter may be assigned, like paths or boolean values.

88a0320d62 [Makefile] remove mkinitcpio dependency (#136)
Errata commit:
This commit has no substantive code change.
This commit is provided only to document a correction to a previous commit message.
This pertains to commit object 87b816345b

Due to improper handling, the aforementioned commit message is incorrect.
Correct message is :

[Makefile] remove `mkinitcpio` dependency

The mkinitcpio binary is not available even on Arch,  when building in a
clean environment (e.g. building distro packages in a clean chroot).

This causes the mkinitcpio hook  to not be present in the final package,
which is resolved by this commit, by adding a `make` switch. This switch
allows users to explicitely turn on inclusion of the hook.

[uninstall:] don't remove non-existent folders

This prevents some warnings being output when on a non-Archlinux system,
without a previously installed initcpio hook, a `make uninstall` is per-
formed.

These three folders should _only_ be deleted if they had been mistakenly
created during `make install`.

d68fdf5fff Adds a new config variable "GRUB_BTRFS_ROOTFLAGS" (#133)
Script:

Improves the rootflags option in the kernel command line:
- Remove "rw" flag.
- Parse fstab mountoptions and add them to rootflags:
Adds functionality to read in  snapshot specific mount flags
from the respective fstab and uses them in combination with the new 
config option, while the latter is prioritized.
Both places can, but don't need to define mount flags. If either of them
doesn't, it will simply not be taken into account.

Config file:

Adds a new config variable "GRUB_BTRFS_ROOTFLAGS":
- The new variable is used to include user-defined rootflags in the 
kernel command line of generated snapshot bootmenu entries.
See config file for more infos.

87168d2d50 [Makefile] Modifies install/uninstall target. Adds help target (#135)
Makefile:

Install target:
- Added "uninstall" and "help" target to ".phony".
- Hook initcpio will be installed only on Arch Linux like distributions.

Uninstall target:
- All commands are in silent mode.
- "rmdir" command will not interrupt the uninstallation if the folder does not exist.
- Remove "-r" option to "rm" command.
- Fix a mistake in deleting the "readme" file.
- Uninstalling the "grub-btrfs.cfg" file uses the "GRUB_BTRFS_GRUB_DIRNAME" variable.
- Delete initcpio folder if not on Arch.
- Delete "grub-btrfs" docs and licenses folders.

help target:
- Add "help" target.

Modify the function which is used to ignore a path.
@ shouldn't be hardcoded.
Create 2 separate functions to ignore a specific path or prefix path.
In specific path, only exact paths are ignored.
In prefix path, any path starting with the specified string will be ignored.
e.g :
if specific path = @, only @ snapshot will be ignored.
if prefix path = @, all snapshots beginning with "@/..." will be ignored.

6ff1fc7127 grub script: improve snapshot listing performance (#93)
Btrfs filesystems may be slow when listing snapshots and calculating
space usage for each.
And that space information is not needed and never used in the scipt.

So, add --disable-ununsed-space to all calls to btrfs.
